RELATED APPLICATION

The present international patent cooperative treaty (PCT) application claims the benefit of priority to Chinese Patent Application No. 201410003618.3, filed on Jan. 3, 2014, and entitled “Multimedia Processing Method and Multimedia Apparatus”, which is hereby incorporated into the present international PCT application by reference herein in its entirety.

TECHNICAL FIELD

The present application relates to the field of multimedia technologies, and in particular, to a multimedia processing method and a multimedia apparatus.

BACKGROUND

Currently, a multimedia apparatus generally includes two parts: image display and sound playback. Since image display and sound playback are generally completed by different devices, the two parts generally are associated with each other only in time, but not in space. The size of common media apparatuses varies greatly, ranging from a few inches (such as a mobile phone device and a tablet computer) to tens of inches (such as a laptop, a desktop, and a television screen) and even to hundreds of inches (such as an outdoor advertising screen), and accordingly the size and distribution of corresponding sound player devices also vary greatly. Most of current video file formats fail to take spatial information of sounds into account, making it difficult for a client to accurately reproduce the sound effect.

In a second example aspect, an embodiment of the present application provides a multimedia apparatus, comprising:

DETAILED DESCRIPTION

Embodiments of the present application are further described in detail below with reference to the accompanying drawings (in which like elements are denoted by like reference numerals) and embodiments. The following embodiments are intended to describe the present application, but not to limit the scope of the present application.

As shown in FIG. 1, one example implementation of the embodiments of the present application provides a multimedia processing method, comprising:

-   -   S110: obtaining, according to sound data, sound information that         corresponds to a sound having at least one predefined feature;     -   S120: analyzing image data associated with the sound data and a         current image display parameter and determining a display area         corresponding to the sound information;     -   S130: obtaining, according to the display area, information         about a perceptual sound source location that corresponds to the         sound information; and     -   S140: processing the sound data according to the information         about the perceptual sound source location and a current sound         playback parameter to obtain processed sound data corresponding         to the information about the perceptual sound source location.

According to at least one technical solution of the embodiments of the present application, relevant sound data and image data are processed, to cause processed sound data to adapt to a current sound playback module and a display module, so that for multimedia apparatuses of various sizes and distributions, the sound effect of sound information corresponding to the sound data and the image data can be accurately reproduced, thereby improving user experience.

The steps of the method of the embodiments of the present application are further described below.

-   -   S110: Obtain, according to sound data, sound information that         corresponds to a sound having at least one predefined feature.

In this example implementation, the at least one predefined feature comprises at least one of the following: a frequency, a period, a variation rule, and a feature value corresponding to a feature extraction algorithm. Herein, when the at least one predefined feature is a feature value corresponding to a feature extraction algorithm, the sound having the at least one predefined feature means the sound having the feature value, that is, the feature value can be obtained by processing sound data corresponding to the sound by using the feature extraction algorithm.

An example implementation of the step S110 comprises:

-   -   by using a pattern matching algorithm such as Neural Network or         Gaussian Mixture Model, recognizing the sound having the at         least one predefined feature in the sound data, and then         obtaining the sound information corresponding to the sound.

For example, pattern matching is performed for the sound data by using the pattern matching algorithm, and it is found that the sound data contains data corresponding to a voice. In this case, the sound having the at least one predefined feature is the voice. For example, the at least one predefined feature of the voice comprises: a particular period, spectrum, short-time energy and the like. When it is determined by using the pattern matching algorithm that the sound data contains a sound component having the particular period, spectrum, short-time energy and the like, it is considered that the sound data is contains voice-related data, and in this case, sound information corresponding to the voice is then generated.

In the embodiments of the present application, the sound information comprises object information corresponding to the sound. For example, an object corresponding to the voice is a person; or for example, when the sound is recognized as a bark, the object of the sound is a dog.

Certainly, in some example implementations, the sound information may be some particular feature values of the sound, such as the period, the frequency, or a feature value corresponding to an algorithm. In subsequent steps, matching of feature values is directly performed between the particular feature value and a feature value of a corresponding image in the image data, without the need to perform semantic recognition.

In an example implementation, when the sound data is multi-track sound data, not only the foregoing sound information, but also an original sound source location corresponding to the sound can be obtained according to the multi-track sound data. For example, an original perceptual sound source location of the sound is calculated by using differences between sound data components, corresponding to the sound, in sound data of different tracks based on a method such as time difference of arrival (TDOA). The perceptual sound source location herein refers to a sound source location, corresponding to a sound, formed in the brain of a user after hearing the sound.

-   -   S120: Analyze image data associated with the sound data and a         current image display parameter to determine a display area         corresponding to the sound information.

In an example implementation, the step S120 comprises:

-   -   analyzing the image data to obtain image content information         corresponding to the sound information; and     -   obtaining the display area according to the image content         information and the current image display parameter.

In this example implementation, by using an image recognition and segmentation method, at least one image area can be obtained by segmenting an image corresponding to the image data, and an image area corresponding to the object information of the sound in the sound information is found in the at least one image area, and then image content information corresponding to the found image area is obtained. Herein, the image content information comprises: image area information (for example, information about the location in the image), object information corresponding to an image area, and the like.

In other example implementations, the image data may comprise image metadata, where the image metadata comprises image area information corresponding to all objects in an image corresponding to the image data. For example, the image corresponding to the image data contains a person, a dog, a wall, and a chair, and then the image metadata comprises:

-   -   an object 1: a person; an image area corresponding to the object         1: (O1x1, O1y1; O1x2, O1y2);     -   an object 2: a dog; an image area corresponding to the object 2:         (O2x1, O2y1; O2x2, O2y2);     -   an object 3: a wall; an image area corresponding to the object         3: (O3x1, O3y1; O3x2, O3y2); and     -   an object 4: a chair; an image area corresponding to the object         4: (O4x1, 43y1; O4x2, O4y2).

Certainly, in other example implementations, the image metadata may comprise more detailed information, for example, various parts of a person (head, arm, torso, leg, and the like) and corresponding image areas; and may further comprise some feature information of an object, for example, features of a person further comprise: child, male and the like, and features of a dog further comprise: black, Labrador and the like.

In this example implementation, image area information corresponding to an object can be found, without the need to perform processing such as image recognition and segmentation on the image data, in the image metadata of the image data directly according to the object information corresponding to the sound information, for example, according to that the object is a dog.

Certainly, in another example implementation of the embodiments of the present application, the image area corresponding to the sound information may also be obtained by directly performing matching between the corresponding particular feature value in the sound information and the feature value of the image corresponding to the image area, as described in the step S110.

In this example implementation, the current image display parameter comprises: the size and location information of a current overall display area. A display area of the image area in the current overall display area can be obtained according to the information about the location of the image area in the image.

In another example implementation, the step S120 comprises:

-   -   analyzing the image data and obtaining at least one image         content information and at least one display area respectively         corresponding to the at least one image content information         according to the current image display parameter; and     -   determining the display area corresponding to the sound         information in the at least one display area according to the         sound information and the at least one image content         information.

In this example implementation, by using the method described above, image recognition and segmentation may be performed for all objects in the image corresponding to the image data to obtain image content information that comprises the image areas corresponding to all the objects and the object information corresponding to the image areas, and then display areas respectively corresponding to the image areas are obtained according to the current image display parameter.

Then, the display area corresponding to the sound information is found from the display areas according to the sound information, for example, by performing matching between the object information corresponding to the sound and the object information in the image content information.

In some cases, for example, when multiple persons are present in the image corresponding to the image data, if a sound corresponding to a voice is detected in the sound data, it may be difficult to determine the person corresponding to the voice. Therefore, in the embodiments of the present application, when the sound data is multi-track sound data, an original perceptual sound source location corresponding to the voice can be obtained by using the method recorded in the further description of the step S 110, and therefore, the object corresponding to the sound information can be more accurately determined according to the original perceptual sound source location and the location of each object in the image. In addition, by using the perceptual sound source location corresponding to the sound, a range to be matched against an object corresponding to the sound can be reduced in the process of determining a corresponding display area in the step S120.

-   -   S130: Obtain, according to the display area, information about a         perceptual sound source location that corresponds to the sound         information.

In the step S130, the perceptual sound source location may be determined according to the location of the display area in the overall display area. For example, when the display area corresponding to the sound information is in the left of the overall display area, the obtained perceptual sound source location is also in the left.

In addition, depth information of the perceptual sound source location and the like may also be determined according to the size of the display area. For example, according to the principle that a closer object appears larger, the larger the corresponding display area of an object in the overall display area is, the closer its corresponding perceptual sound source location is to an audience, and vice versa.

-   -   S140: Process the sound data according to the information about         the perceptual sound source location and a current sound         playback parameter to obtain processed sound data corresponding         to the information about the perceptual sound source location.

In this example implementation, the current sound playback parameter comprises parameter information of the current sound playback module, for example, a parameter such as the distribution, size or performance of the sound playback module.

In an example implementation, the sound playback module comprises a plurality of sound playback units.

The current sound playback parameter comprises: current parameter information of the plurality of sound playback units.

Herein, the parameter information of the sound playback unit comprises, for example, a parameter such as the distribution, size or performance of the sound playback unit, or a sound data track corresponding to the sound playback unit.

In this example implementation, the processed sound data corresponding to the information about the perceptual sound source location means that when the sound playback module corresponding to the sound playback parameter plays the sound according to the processed sound data, a user who hears the sound having the at least one predefined feature will think that the sound source location of the sound corresponds to the information about the perceptual sound source location.

The step S140 of this example implementation is further described below by using examples in which the sound data is single-track sound data and multi-track sound data respectively.

In an example implementation, when the sound data is single-track sound data, and the sound playback module comprises a plurality of separately distributed sound playback units, the processing the sound data according to the information about the perceptual sound source location and a current sound playback parameter may be:

-   -   determining a sound playback unit corresponding to the         perceptual sound source location according to the information         about the perceptual sound source location and the current sound         playback parameter, and processing the sound data to cause the         sound corresponding to the sound information to be played only         by the determined sound playback unit.

For example, the sound playback module is a transparent thin-film sound playback module disposed on the surface of the display area, and is divided into a plurality of sound playback units distributed along the surface of the display area, and when the object corresponding to the sound information is a bark, the sound data is processed to cause a sound playback unit corresponding to the location of a dog's head in the display image to play the bark.

In another example implementation, when the sound data is multi-track sound data, and the sound playback module comprises a plurality of separately distributed sound playback units, the processing the sound data according to the information about the perceptual sound source location and a current sound playback parameter may be:

-   -   adjusting the phase and/or amplitude of a sound data component         corresponding to the sound in sound data of each track according         to the information about the perceptual sound source location         and the current sound playback parameter sound data to cause the         sound played by the sound playback module according to the         adjusted multi-track sound data to give the audience a feeling         that the sound is produced from the perceptual sound source         location.

In one example implementation, for example, a new sound data component corresponding to the sound may be synthesized according to the perceptual sound source location and the parameter of the sound playback unit by using a wave field synthesis (WFS) algorithm, and then the sound data is adjusted according to the sound data component, so as to obtain the processed sound data. Certainly, in addition to the foregoing WFS algorithm, other suitable sound synthesis algorithms may also be used in the embodiments of the present application to obtain the processed sound data.

As shown in FIG. 2, in another example implementation of the embodiments of the present application, after the processed sound data is obtained, the method further comprises:

-   -   S150: Play the sound according to the processed sound data.

In the example implementation as shown in FIG. 1 or FIG. 2, the method may further comprise:

-   -   storing at least one of the following information: the sound         information, the display area, the perceptual sound source         location, and the processed sound data.

One or more pieces of data in the foregoing process are stored, so that when the same multimedia data (comprising the sound data and the relevant image data) is played by a same or similar multimedia apparatus, some data processing steps can be omitted, thereby improving the efficiency.

It should be understood that in various embodiments of the present application, the value of the serial number of each step described above does not mean an execution sequence, and the execution sequence of each step should be determined according to the function and internal logic thereof, and should not be any limitation on the example implementation procedure of the embodiments of the present application.

-   -   a display module 550, configured to perform displaying according         to the image data; and     -   a sound playback module 560, configured to play the sound         according to the processed sound data.

The advent of a transparent loudspeaker, particularly a thin-film transparent loudspeaker (for example, a transparent gel loudspeaker, in which another layer of transparent saline gel is added on the surface of a transparent ionic gel thin film, and after being electrified, the entire thin film rapidly deforms, to produce a full-range sound) makes it possible to apply the loudspeaker to display screens. For example, if a layer of thin-film transparent loudspeaker is disposed on the surface of a display area of an electronic device having a display function, and therefore there is no need to dispose a loudspeaker around the display area of the electronic device and there is no need to connect an external loudspeaker to the electronic device. The applicant of this application finds that when the sound playback module of the multimedia apparatus is the foregoing transparent loudspeaker applied to display screens, a phenomenon of inconsistency between the sound playback effect of the multimedia apparatus and the space of the displayed picture becomes more obvious as the size of the display screen varies. Therefore, when the foregoing method and apparatus of the present application are applied to the multimedia apparatus having a transparent sound playback module, the phenomenon of inconsistency between the sound playback effect and the space of the display picture can be well solved.

For example implementation procedures of the foregoing modules and units, refer to the corresponding descriptions in the method embodiments shown in FIG. 1 to FIG. 2, and details are not described herein again.
